Flange 14 is provided with a plurality of apertures 15 for the reception of securing ele ments 16 which extend through flanges 17 of a pair of leg members 18 for rigidly securing head 10 and leg members 18 together. Flange 12 intermediate the ends thereof is widened as indicated at 19, coextensive with widened portions 14 and formed in widened portions 19 is a bearing 21. Integrally connecting widened portion 14 and bearing 21 is a plurality of radiating reinforcingribs 22- reception of suitable securing elements which extend through and rigidly secure the oppo- The opposite end head 23 is similar in consite ends of a semi-cylindrical casing 26 to end heads 10 and 23.

Supported on and secured to flanges 12 of end heads 10 and 23 are the plane flanges 27 of hood heads 28, which as shown in Figures 9, 10 and llare quadrant shaped and are provided with apertured curved flanges 29, reinforcing ribs 31, and bearing cap receiving portions 32. The opposite ends of a casing section 33 are rigidly secured to flanges 29 by suitable securing devices extending through casing section 33 and apertures 34 in flanges 29. Bearing caps 35 are secured to widened portions 19 of flanges 12 by suitable securing elements 36 and each cap is provided with a lubricating duct 37 for lubricating the opposite ends of a drum drive shaft 38 which are journaled in bearings 21 and caps 35.

Formed integrally with head 10 is a bearing 39 in which is mounted a stub shaft 41 on which is journaled a sprocket wheel 42. Secured tosprocket wheel 42 by securing bolts 43 is the hub 44 of a pinion 45 which meshes with a gear 46 fixed to one end of drum drive shaft 38. End head'lO is provided with a threaded boss 47 and corresponding hood head 28 is provided with a similar boss 48, said bosses receiving securing elements extending through ears 49 and 51 of a gear and pinion housing 52, which as shown in Figure 1 is spaced from adjacent heads 10 and 28 to provide room for a sprocket chain 53 which extends about sprocket wheel 42 and a similar sprocket wheel 54 secured to shaft 55 of an electric motor 56 which is secured to a suitable support 57 on casing 33. Bearing cap 35 at the discharge end of the machine is provided with a grease cup 58 while the duct 37 in cap 35 at the drive end of the machine has threaded therein to the end of a tube 59, the outer end of which is supported by a clip 61 carried by ear 51 and a suitable grease cup 62 is carried by the outer end of tube 59. A grease cup 63 is attached to stub shaft 41 for lubricating sprocket wheel 42 through a duct 64.

Connected into end head 23 as at 65 is a water pipe 66 which has in communication therewith outward of connection 65 a steam pipe 67. Water pipe 66 is provided with a valve 68 outward of the connection of steam pipe 67 therewith and steam pipe 67 is provided with a valve 69 by means of which valves water is admitted into the chamber defined by end heads 10 and 23 and casing 26 at any desired temperature regulated by the amount of steam admitted with the water.

Casing 26 is depressed to form a downwardly inclined discharge trough 71, or if desired trough 71 may be separate from casing 26 and may be secured thereto by any suitable means. Secured to flange 14 and an extension 72 of trough 71 is a casting 73 provided with a vertically slidable gate 74 which is controlled by a bell crank lever 75 pivoted as at 76 and having a lost motion pivotal connection 77 with gate 74, lever 75 being provided with a suitable operating handle 78. A hood 79 of substantially quadrant shape in side elevation and comprising sides 81 and a curved face or cover portion 82 is pivotally supported in grooves 83 in bearing caps 35 to permit a swinging movement of hood 79 to open and close the'interior of the washer. Hood 79 is provided with a pair of manipulating handles 84 and the sides 81 thereof rest substantially in contact with the opposing faces of end heads 10 and 23 and hood heads 28 as indicated by dotted lines in Figures 2 and 3, and hood 79 is further provided with a flange 85 adapted in closed sosition thereof to abut a flange 86 secured to casing 26 and adapted in open position thereof to abut a flange 87 secured to casing 33. End heads 10 and 23, hood heads 28, casings 26 and 33 and hood 79 define a closed cylindrical chamber in which is disposed a drum 88' for receiving the material to be washed or cleaned.

Drum 88 comprises a pair of heads 89, each of which as shown in Figures 12 and 13 comprises a plate 91 provided with a laterally extending flange 92 which as is clearly shown in Figure 121s of uniform wave-like formation and integrally connecting plate 91-, flange 92 and a central hub member 93 are a plurality of radially extending reinforcing ribs 94. Heads 89 have the hub members 93 thereof fixed to shaft 38 for rotation therewith and secured to flanges 92 are the opposite ends of a sectional casing 94, which when assembled is of wave-like form corresponding to that of flange 92 as clearly indicated in Figure 3.

Casing 94 is formed of a plurality of sections 95 which have their ends secured to flanges 92 and have their sides outwardly turned to provide flanges 96 which flanges are secured together in abutting relation by securing means 97 as indicated in Figure 3, thus providing the complete scalloped or wave-like drum 88. Casing 94 is interrupted at a point opposite hood 79 and is provided with a removable section or gate 98 so that upon opening hood 79 access can be had to the interior of drum 88 through section or gate 98;

Each section 95 and gate 98 are of a foraminous construction which are formed by punching out portions of the metal to form 18) in order to prevent sharp cutting surfaces which would be apt to injure the parts being treated.

In the operation of the machine a suitable number of animal parts to be washed or cleaned are disposed within the drum 88 upon opening hood 7 9 and gate 98, for example parts such as beef and hog stomachs being turned inside out to expose the side bearing the tenacious material, after which gate 98 I and hood 79 are closed.

mitted into the chamber surrounding'the drum88 through valve 68 and a desired amount of steam is admitted with the water through valve 69 whereupon motor 56 is'set' into operation which through the sprocket 54:. chain 53, sprocket 42, pinion 45, gear 46,

and shaft 88 imparts rotation to drum 88, which due to the successive reductlon drive. connections is rotated slowlyas compared to the rotation of motor shaft 55.

Upon the rotation of drum 88 the animal parts will be carried forwardly and upwardly by the combined action of burs 101 and the 3 wave formation in casing 9a to a oint where the angle of the supporting'portio-ns of burs 101 and wave formations is such that the parts will fall therefrom or slide down over the rough wave-like surfaces. In this repeated movement the parts are subjected to an abrading or scraping action from burs 101 and the wave-like surfaces which scrapes ofli' portions of the viscousmembrane which it is desired to remove.

Water is then ad-" Furthermore the con 'tinuous rotation of drum 88 by means of burs .101 and the wave like surfaces will cause a to said last heads; co-operating bearings and bearing caps supported by said first heads, a

hood revolvably supported by. said bearing caps; a shaft supported in said bearings; a sinuous foraminous revolvable drum.v secured to said shaft; and means for imparting'rotation to said shaft.

2. A machine for cleansing and scraping animal tissues or similar materials, comprising a casing, a revolvable drum mounted for rotation within'said casing and adapted to receive said materials, the walls of said drum being constructed of sinuous foraminous material theforaminations being formed so as to provide scraping projections extending toward theaxis of said drum, the sinuous form of said drum being such asto provide wide grooves separated by ridges of relatively great width so that the'material will be caused to successively enter said grooves and be moved over said ridges and scraped by said projections as said drum is being rotated.

3." A machine for cleansing and scraping animal tissues or similar materials comprising a casing, adrum mounted for rotation in said casingv and adapted to recelve the ma terials to be cleansed and scraped, said drum being provided-with a multiplicity of openings extending through its side walls, said side walls being longitudinally corrugated 'to provide alternate grooves and ridges of relatively great width compared to the diam eter of said drum, whereby said materials are caused to successively enter said grooves and slide over said ribs and to be scraped and cleansed by the relatively sharp corners provided by said openings in said drum.

In testimony whereof I affix my signature. W'ILLIAM B. ALLBRIGHT.
